Filmmaker Peter Jackson thinks too many First World War movies are "cliched" and too "serious". "I think First World War movies are in danger of being a cliche. They take the most basic concept, which is soldiers going over the top, and that's all the films are. I'm just not excited about most of them," Jackson told Sunday Times Culture magazine.

He added: "Also, and this is going to sound weird, First World War films are often too serious. They show troops having a miserable time, whereas, if you are in a bad place, humour comes to the surface. The soldiers didn't have self-pity. There are a lot of laughs.
